Abstract: A content delivery network (CDN) includes a plurality of CDN components including at least one CDN rendezvous mechanism and at least one control core. The CDN components are controlled by control core data from the at least one control core. Some CDN components obtain CDN resources including control core data from at least some other CDN components. The CDN components use the CDN rendezvous mechanism to select one or more CDN components from which to obtain CDN resources.

Abstract: Embodiments herein include methods and systems for use in delivering resources to a client device over a local network. An exemplary system comprises a plurality of caching devices operable to cache resources on behalf of a plurality of content providers, and a local caching device communicatively situated between an access network and the client device, wherein the access network is communicably situated between the plurality of caching devices and the local caching device. The local caching device is operable to retrieve a requested resource from at least one of the plurality of caching devices, deliver the requested resource to the client device over the local network, and store the requested resource for future requests by other client devices.

Abstract: A content delivery network (CDN) includes a control core; and a plurality of caches, each of said caches constructed and adapted to: upon joining the CDN, obtain global configuration data from the control core; and obtain data from other caches. Each of the caches is further constructed and adapted to, having joined the CDN, upon receipt of a request for a particular resource: obtain updated global configuration data, if needed; obtain a customer configuration script (CCS) associated with the particular resource; and serve the particular resource in accordance with the CCS.

Abstract: A content delivery network has at least a first tier of servers. A content delivery method includes, at a first server in the first tier of servers, obtaining a request from a client for a resource. If the resource is available at the first server or at a peer of the first server, then the resource is served to the client from the first server. Otherwise, it is determined whether the resource is popular, and if the resource is determined to be popular, then the first server obtains the resource and the first server serves the resource to the client. If the resource is determined not to be popular, the client is directed to a second server, not in the first tier of servers, and the second server serves the resource to the client. The second server may be in a second tier of servers or it may be an origin server.

Abstract: A content delivery network (CDN) includes multiple cluster sites, including sites with streaming media servers, caching servers and storage devices accessible to the caching servers for storing streaming content. Interface software is configured to initiate retrieval, by a caching server, of electronic streaming resources from the one or more storage devices in response to requests for the electronic streaming resource received by the streaming media server.
